Specification of Letters Patent.

Patented May 16, 1916.

Application filed November 17, 1913. Serial No. 801,538.

T0 all whom t may concern Be it known that I, RICHARD WEBB BUR- Nnr'r,of the city of Montreal, in the Province of Quebec, Dominion of zen ofthe United States of America, have invented certain new and usefulImprovements in the Doors of Hopper-Bottom Cars; and I do hereby declarethat the following is a full, clear, and exact description of the same.

My invention relates more particularly to the construction of the hopperwalls or flanges of trough-doors to form pockets for receiving theflanges of the door oredges of the walls as the case may be in order toprevent leakage of granular materials at the ends of the doors; theobject of the present invention being to provide an alternativeconstruction to that disclosed in my pending application Serial No.655253 filed October 17, 1911, for improvements in convertible cars. Tothis end I provide the edges of the hopper walls or the flanges of thedoors with a strip of metal and a distance piece separating the stripfrom the wall or ange.

For full comprehensionl however, of my invention reference must be hadto the accompanying drawings forming a part of this specification inwhich similar reference characters indicate the same parts, and wherein:

Figure 1 is a detail perspective view of the hopper wall provided withmy invention and showing a portion of the door in position to engage thepocket; Fig. 2 is a transverse vertical sectional view through ayportion of the hopper bottom of a car and'illustra-ting my invention;Fig. 8 is a similar view to Fig. 1 of a door with its langeprovided witha pocket according to mypresent invention.

Canada, a citi` The hopper wall is indicated at b and the door at c, thedoor being of trough crosssection thus presenting flanges c. Accordingto my invention the members, the hopper-walls or door-flange each have ametal plate d and a distance piece e secured thereto by rivets f thusforming a pocket to receive the other member, the thickness of thedistance piece being equal to that of the member to be received in thepocket, while 'the edges of the pocket thus formed are flared as at g tofacilitate entrance thereinto.

What I claim is as follows 1. The combination with a hopper-wall memberand the flange of a troughed door, of a strip of metal and a distancepiece secured to the outside of one of the said members along the edgethereof for the purpose of forming a pocket to receive the other member.

2. In a dump-car the combination with a hopper having hopper-walls and adoor for controlling the discharge therefrom, the ends of said doorbeing bent at right angles to the main length thereof toward saidhopper-walls; of a strip of metal and distance piece secured to theoutside of each of said walls along one edge thereof for the purpose ofpresenting a pocket to receive the bent ends of the door when the latteris in closed position the free edges of the strip'and the wall towhichit is attached being oppositely bent to present a flared mouth.

In testimony whereof I have signed my vname to this specification in thepresence of two witnesses.
